22 / 04 MERCURY OF ANGKOR PROPER Main
Ecliptic longitude from Sun = -
(Meridian of Phnom Bok)
OBSERVER(1) : intersection of the meridian of the PHNOM BAKHENG summit with southern enclosure of Royal Palace (13.444754° N ; 103.855927° E) at 9 kam to the south of Phnom Dei, 3 KY to the north of Bakheng summit, 17 KY to the west of Bakong and 16 KY to the north of the same temple ie on a 22 / 04 solar apsides line drawn from the latter ( arctang(16/17) = 43.264° ; error = 0.0087°)
Radius (Rd) = 2.84253 km = 3.77766 KY
Az. = 0.127°
Runs through the centre of the central sanctuary of the Takeo temple
Radius = quarter of perimeter of takeo’s external enclosure.
(Glaize: The external enclosure wall forms a rectangle of 120 metres by 100)
The centre of the epicycle is located:
The parallel of Phimeanakas and the loxod. from Sun equant to Sun are tangent to the epicycle.
Radius (Rs)= 1.04234 km
= 1.38525 KY
The loxodrome from Ta Prohm to Krol Ko is tangent to the epicycle
The parallel of Victory Gate determines a Sighra ratio with respect to the centres of Thommanon and Chau Say temples.
The Chau Say temple has dimensions related to the Sighra ratio:
57.5 / 157 = 0.36624
with 157 m = 5 kas = perimeter of enclosure (median axis) and 57.5 m = diagonal of enclosure (outer corners)
Azimuth indicated by the loxodrome from the Mercury’s observer to the Linga of the Phnom Bok.
Error = 0.1°
The circumference C of the Linga is 3.77 m.
The perimeter P of the platform is equal to 48 m
C / P = 0.07854
Now, the eccentricity "2e" (equant) of Mercury is 0.0778
The planet is located on the axis of the Ta Prohm temple.
= 0.11057 km
Az. = 183.273°
Dist. from obs.
(Re) = 0.22114 km
Az. = 183.273°
Remarks: Rm/Rd = 0.0389 ; D/Rd = 0.0389; Rs/Rd = 0.3667
221.14 / 603 = 0. 3667 with 221.14 m = diameter of the manda epicycle and 603 m = distance from Takeo temple to inner embankment (shoreline) of East Baray.
2 * 603 * 0. 0389 = 46. 9 m (the upper platform of Takeo is a 47 metres square)
77 / 210 = 0. 3667 with 77 m = and 210 m = distances from Chau Say Tevoda to, repectively, parallel of Victory Gate and Thommanon.
